There's no doubt that Uncharted: The Nathan Drake Collection is an attempt to rekindle interest in the franchise (and score some extra sales) ahead of Uncharted 4's release next year. However, that doesn't mean that Bluepoint Games' PlayStation 4 port of the first three Uncharted games is a simple cash-in. The team at Digital Foundry has conducted a shot-by-shot comparison of the anthology's trailer with the respective moments in the PS3 games, and it's clear that there are many, many little visual upgrades (beyond just the jumps to 1080p and 60 frames per second) that add up to a lot. More detailed objects are everywhere, lighting is more natural and cinematic depth-of-field effects occasionally pop up -- just take a look at Nathan and Sully in the PS4 edition (pictured at left) versus its PS3 counterpart (right). There are even elements that weren't there at all before. The games treat fire and dust differently than they did in the past, and you'll see new details like low-hanging clouds.
